That means one single machine is rendering the game for all players, and with modern game engines that can reliably scale to maybe 4 players. Even then, that would come at the cost of graphical fidelity compared to practically any other game on the market. (Some modern games get away with it because of distance from the TV obscuring interlaced rendering or checkerboard rendering) Assuming you build on this by having some unsecured shared state, e.g.: hypervisor shared memory, and all clients rendering their own game -- that means you're now restricting gaming by geographic region. If you do that and segregate players by area, you would fragment the playerbase and eventually kill off the game as any loss of popularity snowballs.
